I was working in an 8 inch square hand bound journal I’d made using the OLD Gutenberg paper from Hahnemühle.
(Remember I don’t recommend the new version of Gutenberg now being sold. It still binds up great, but it doesn’t work with wet and mixed media as grate as the old paper.)
I love square or almost square books, but sometimes you just need to turn things on on end to have the space that you need.
Use your journal in a way that works for you!
